Be it known that I, GEORGE LISPENARD, a citizen ofthe United States, residing' at Nen" York; (Brooklyin) in the county vof Kings and State of New York, have invented a certain new and useful Choking-Machine for Fire-Cracker Bodies or the Like, of which the following is a specification.

lily invention relates to machines for mak ing a choke or plug to clbse the end of a fire-- Y cracker or other like body.

Azo

In au aapplication filed by me on the 27th day of May, 139B, Serial No. USLQl, l have described a choke for a fire-cracker in which the body is made of alseries of convolutions of pulpy paper, such as Chinese paper or the like, and the present application relates to a machine which-may he employed .inproducing the choke Adescribed in said application. l

In forming a choke fora fireciackcr by machine, where the pressure is constant, considerable y d'iflicnlty has been encountered where-the body ef the cracker has been made of soft paper in causing` the body of the cracker to withstand the pressure necessary to efficiently form the choke. lVhen the body A ofthe paper is made up of a number of convolutions of comparatively thin and hard paper, it presents sulllcicnt resistance, both longitudinally' and transversely, to offset the neccssarypressurc used lnlorrningthe choke, but when a lire-cracker body is employed in which the convolntions are made of thick and pnlpy paper, there being necessarily but few of them,'the body presents comparatively litlle resistance transversclyor longitudinally to the aclion ol' the choking means.

All' present inver'rtion therefore relates to a machine by means el which an ellicient choke calr be .made in a lire-cracker body composed ol a Yew convoiutions of comparatively thick and pulpy paper, such as is known in the tradeas (5hincse paper.

My invention therefore prinn'rrily consists in a suitable bod-plate, a serios o1 pins grouped closely together and ln ving their upper ends formed on in angle converging to a point central to the grr,\r1p,'thepiusaet ingr to detach one or more ot' the intcriorconvolutions of the body from the exterior convolntions and compress the detached or disturbed portions of the convolutions,combined with means for supporting the fireeraclcr body while the pins areactiug, above rccited, so as to prevent longitudinal trzmsvcrf-.ic distort-imi oli" said bodies.

lu un applicatimi filed by one Charles L. Curtis on the 7th day of llcbruary, 1898, Scrial No. 669,370, a machine' described for formino` the choke in a lire-cracker body. rlhis machine was designed to operateon iirccracker bodies formed of a nu mber of convo lutiens oi' comparatively hard and thin paper in which cmnparatively a great number ol convolutions were employed, the large number ol` convolutions and the stiffness of 'the paper ollering lateral and longitudinal resist` ance to the operation ol.' the machine while forming,` the choke. ln that machine also pins were employed, but the wedge action olthe pins was not as great as is contemplated in my present invention, and they were merely used for the purpose of separating some of the interior eonvolutions from the exterior convolutions, the linal act of forming the plugl or choke being due to the operation of a plunger which bodily moved all the separated convolntions inwardly and compressed them to a marked degree into concentric rings which formed abutments within the bore of the body. By reason of the toughness ol the paper operated upon it Was 'necessary to employ during' the plugging operation a central pin or rod, about which the choke was formed in order te leave a su llcient opening, into which was subsequently passed the dischargingstem. lu my present invention I entirely eliminato the subsequent operation of the lunger .o form the choke and form it by the action of the plus, at the same time forming,r the choke immediately about the stem, thus avoidina)` the necessity es." the subsequent operation ot inserting the stem after the choke is formed.

lily invention also contemplates means whereby the chokes at bot-h ends of the body can be formed either' simultaneously while `the stein is in place or at different periods, both, however, without removing the body from the support in which it is placed.

My invention further contemplates a machine in which gangs oi' these separate chokeforming devices are employed in which the elements thereolI cooperate toform an efficient time and labor saving machine.

My invention therefore consists substantially in the construction and combination of parts hereinafter described, and further pointed out in the claims.

In the (li'awings forming part of this specification, Figure l is a side elevation of the machine embodying my invention; Fig. 2, an end elevation thereof; Fig. 3, an under side plan view o1" tue movable carrier-fram e, partly in section, on the liuc .n a?, Fig. 1, looking in the direction ol' the arrow; and Fig. 4- is a plan view of the base of the machine, partly in section, on the line y y, Fig. 2, looking in the direction of the arrow.

Similar numerals of reference indicate corresponding paris throughout'. the several views.

l believe that the several features of my invention are entirely new with me, and therefore l do not intend to limit myself to A thespcciiie construction of the machine herein shown and described, but prefer the same for many reasons.

The embodiment of my invention, as illustrated in the accompanying drawings, consists, substantially, as follows: At 1 isasuitable bed-plate supported in the desired manner. On thisbed-plate are secured upwardlyextending choking-pins 2, preferably three in number, set equidisiant apart, each pin having at its upper in'ner portion an inclined face 3, the incline ol' which converges toward the mutual central axis ot' the grouped pins, the incline forming entrant and compressing points. About these pins at a distance apart corresponding with the diameter of the firecrackcr body to be operated upon are secured restraining or steadying pinsa 5, preferably four in number, for a purpose hereinafter described.

rlhe means thus 'l'ar is amply suiiicient to produce the choke described in my applicatonbefore set forth, which is formed as foilows: At i) is a fire-cracher body comprising a series of couvolutions 7 oi paper forminga bore S. The body of the cracker is placed within the restraining-pins 1- 5, the wedgeshaped points of the choking-pins being located at a sufficient distance apart to take in the-'desired number 0L" interior convolutions of the body. At 9 is the stem, the end of which may project out from between the choking-pins, as shown in Fig. 1. A sharp blow on the top of the body will drive it down onto the pins, forcing a number of the interior convolutions 10 of the body away from each other at the places Where the pins enter, the incline or wedge of the pins act.

ing to compress or force the displaced portions of the interior convolutions inwardly toward the steinand to compress the adjacent undisturbed portion ofthe interior convolutions upon each other, as described in my before-mentioned application, which cihciently chokes the end of the bore as against interior forces during explosion and to properly hold the stem in place, as at 11.

'lhus far described it will be noticed that my invention does not require the coperation of other mechanical elements to properly form the choke, as the device, consisting simply of the bed-plate, the upwardly-extending choking-pins, and the steadying-pins, (which might be in the form of a tube,) are all that are essential for the production of the particular form of choke described in my abovementioned application,-the steadyingpins being preferred, because they allow the body to be seen during the choking operationgbut it will be apparent that both time and money can be saved by operating upon a number of tire-cracker bodies at once and to complete the operation of plugging both ends of the body at one time or both ends without re-l moving the bodyfroin the steadyiug-pins. To produce those results i have embodied this portion of my invention a's will new be described.

'lhe bed-plaie l is provided with a duplication ot' theehcking-pins 2 and the steadyingpins i 5, each set of the latter, preferably four, steadying-pins having a separate set of choking-pins disposed between them, and in order to save space on the bed-plate and to cause the two inside pins 5 to support two adjacent lire-cracker bodies l arrange the pins in the direction of their lengths so as to oppose each other, as shown in Fig. 4, the second fire-cracker body from either end of the range of pins resting against the two'inside centering-pins 5. By this arrangement I dispense with a separate and complete set of pins for each body and cause cach set of steadying-pins to support the next fire-cracker body, thus saving space on the bed-plate and expense and reducing the number of parts.

Thus iar it will also be noticed that the operation of forming a choke at one end can be performed by giving a blow to the end of the bodies after they have been placed in position, as indicated in Fig. 1; but in order to form the choke at both ends of the body without removing the body from the steadyingpins l provide the following construction: At 12 are two guide-rods secured in the bed-plate land extending upwardly from the end of the range of steadying-pins. At 1'3is a frame adapted to be moved up and down on said rods, for which purpose handles 14 are provided, which extend outwardly frdm the crosspiece 15 of the frame, and in order to cause said frame to move freely up and down on the rods I form a guideway comprising three seem/o the rollers bearing` against the curved side ol' the :rods 12, the cross-piece l5 being' bifureated, as at l), Fig. 3, .to allow the rods l2 to pass freely up and down, the ends 2O of the projections l!! being` provided with a shaft on which a single outer grooved roller 2l is mounted, which roller bears against the other side of the rod. This forms an etlieientguide 'for the cross-bar l5 of the frame, stcadying it, keepingT it in perfectI alinement, and maintaining its parallelism with the bed-plate, which latter is essential to forming the chokos in the bodies between the lower range ot' steadying-pins at equal and uniform distances from the end of the body and to compress the coi'xvolntions forming the choke in each of the separate bodies to a uniform degree.

liv reference to Fig. 3 it will be noticed that the cross-bar l5 is provided with a series 22 of depenimcT choking-pins, each series comprising three pins 355, arranged and constructed in the same manner as the lower chekingppins 2, and that from each side ot' the series ot' choking-pins depend a further series olf centering-pins 24', located ou a line passing' through the mutual center ot each groupi of choking-pingthc uppeiI and lower series of choking-pins l being in vertical alineinent relatively to each other, while the upper and lowercentering and steadying pins are staggered one in relation tothe other, the upper centeringpins beine; wider apart for a p urposc hereinafter' described.

.as before stated, it is intended to operato the upper movable frame lLl,-e;uifyii1 e the upper range ot' centering and choking pins, by the hand-that is, to cause its range ot cholc` ing-pins to engage the upperend of the bodies while they are held by the si.eadyiru rpins of the lower mage-and in order to raise the frame out oi' contact with the bodies and su'rliciontly remove it therefrom to allow oi the bodies being expeditiously removed from the range of stcadyingpins without hindrance from the pins ot' the upper frame l have provided a countcrweight 25, shown as being secured to a cord 26, passingover pulleys 27 2S, suita ly supported, the other end of the cord being secured to an eye-boit through the cross-bar of the frame. However, instead of using' the counterweight its equivalent, a spring, .may be employed, the frame being;l` moved downwardly1 to torni the choke against the stress of the spring, which when pressure is released from the tramo will raise the traine from the pinsl in its upward position. At any desired heiglu on the red stops may be formed, as by a collar 30, in order to arrest the ascentoi the frame at any desired height.

'lho operation is as follows: '.lhe bodies being placed in position between the -lower steadying-pins, as before described, with the stein in plaoe,as indicated in Fighthe desired number of interior eonvolutions of the body being embraced by the lower range of chokingpins, the frame is mo ed sharply downward,

it'l, passing` causingr the upper ranj'zol eeni'eringpins to embrace the sides ci? the body between the lower steadying-pins, perfectly centering the .Frame over the interior convolutions which it is intended the upper choking-pins shall embrace, and actingr further to steady and brace the bodyduring` the impact received from the frame, the impact being further continued driving the upper range oi choking-pins into the bodies, moving the lower end of the bodies down onto the lower range of choking-pins, i forcing the lower range of choking-pins into the lower end oi" the body, the continuation et' the movement olf the trame forming both the upper and lower ehokes about the stem, the down ward movement of the bodies on the lower range ot choking-pinstbeing finally, if pressure is continued to that point, arrested by the bed-plate, and the downward n1ovement of the trame being arrested by the cross-piece l5 coming in contact with the top of the bodies; and should the pressure of the impact given to the bodies by the movable frame be so great as to tend to distort the contact with the under side of the cross-bar height of the lower steadying-pins being preferably so proportioned that they will be longer or higher from the bed-plaie than the rested on the bed-plate, thus checking the downward movement of the frame and preventing undue pressure being` placed upon the tire-cracker body.

my invention can be embodied in' devices other than the one illustrated wit-hout departing from the spirit ol my invention.

Having described my invention, I claimbination with a stationary bed-plate or support, ot' a group et' upwardly-extendIng pins, said pins having' produced upon their upper portions inclined. or wedgeshaped faces con verging toward the central avis of the group, and upwardlyfextending steadying-pins secured to said bed-plate and grouped about the first-mentioned pins, said steadjingr-pins extending above the chols `g-pins, subetantially as described.
